A human gait temporal parameters calculation algorithm
Rodriguez Cheu, Luis Eduardo | 2017
This paper presents a new algorithm to calculate three temporal parameters of human gait: cadence, swing time and stride time. These values are computed from: heel-strike time, toe-off time and mid-swing point time which can be in turn obtained from the first time derivate of the medio-lateral axis angular velocity of both shanks. The results generated by the proposed algorithm were validated with those of the commercial software Tech MCS Studio of Technaid. The comparison gives a mild difference for cadence and stride time. Aditionally, the new algorithm is a good alternative to the thresholding-based algorithms previously reported in the literature which require a great amount of work dedicated to the manual tuning of their multiple parameters.
